Up the Lewis River
Cougar sits along the Lewis River on SR-503, on the south side of Mount St. Helens near Yale Lake. Full-time homes share the area with cabins and seasonal places, and winters here are colder and snowier than in the valley.
Cabins and seasonal homes
A cabin that sits empty part of the year needs heat it can count on. We service furnaces, heat pumps and ductless mini-splits, and a pre-season check makes sure the system is ready before you arrive for the winter.
Plan ahead when you can
Cougar is at the far end of our service area, so call ahead for maintenance and installs. For a heating failure, call (360) 991-5017. Emergency service is available 24/7.
